2 Claims.

This invention relates to the manufacture of suspenders and like articles, and proposes a method for assembling the operatively folded suspender web and the slide, as an alternative to the method disclosed in my pending application No. 494,378, filed November 8, 1930, patented October 13, 1931, No. 1,827,017, in which the web, prefolded, is placed between the component slide parts, and by an act of pressure upon the whole, the slide parts are integrated into a slide with the web folded therebetween.

The present invention utilizes a one-piece slide, that is to say, a slide in which the frame and middle bar are of one-piece or united, and the novel method involves the step of opening the middle bar at some point to admit the assembled layers of the prefolded web, and the restoring of the middle bar to its normal closed position in the plane of the frame, so that the slide then embraces the folds of the web in the normal and known manner.

The present invention is the converse of the method followed in ordinary practice, for while it is usual to form the fold in the web by threading the web through a preformed slide, in the present invention the slide is folded about the prefolded web.

Other objects of the invention will appear as the following description of illustrative and practical embodiments thereof proceed.

In the drawing in which the same characters of reference have been used throughout the several figures to designate identical parts:

Figures 1 to 4 inclusive, illustrate one form of Figures 7 and 8 illustrate another modification. Figure 9 is a view which may be common to both forms of the invention.

Figure l is a perspective view of one form of slide;

Figures 2 and 3 are vertical elevations, partly in section showing successive steps in one form of the method;

Figure 4 is a plan view of the web and slide parts in the positions shown in Figure 3;

Figures 5 and 6 are perspective views showing other forms of slide amenable to the methods of assemblage proposed by the present invention;

Figures 7 and 8 are elevations showing the web in section and illustrating two steps in a modified method;

Figure 9 is a perspective view showing the completed assembly.

Referring now in detail to the several figures, and first adverting to that form of the invention shown in the group of Figures 1, 2, 3, 4 and 9, the numeral 1 represents a suspender slide made from a single piece of bent wire so as to constitute a substantially rectangular frame 2 and a middle bar 3. The middle bar may be left with its abbutting ends free or they may be joined by a ferrule l as shown in Figure 9 or by any other known and practical means of uniting.

vSuch slides as are shown in Figure 1 are old in the art, but the usual method of inserting the web to form the sliding fold is to thread it through. the spaces between the sides of the frame and middle bar. No one prior to the present invention has contemplated the use of this slide or of any kindred slide in practicing a method by means of which the suspender web may be prefolded and the slide then applied operatively thereto without necessitating the threading of the web through the slide.

The operativeness of the present method is predicated upon the provision of an open or discontinuous joint in the middle bar. Such a joint is shown at. 5 in Figure l, occurring at an intermediate point of the middle bar. By means of this open joint, it is possible to divert or distort the respective portions 6 and 7 of the middle bar until they stand substantially perpendicular to the plane of the frame 2 as shown in Figure 2. A space is thus provided for the introduction of the prefolded suspender web. Figure 2 shows that the portions 6 and 7 of the middle bar have been diverted by means of a spreader 8 having a linear dimension enabling it to fit widthwise within the frame and to press the portions 6 and 7 upwardly and apart until they stand perpendicular to the plane of the frame. The prefolded web is then inserted manually or otherwise in the space between the portions 6 and 7, which web may rest upon the spreader 8 as the latter is re: 5 tracted, until the web engages the frame 2 as shown in Figure 3. The material of which the slide is constructed may be assumed to have some elasticity so that as the spreader recedes, the portions 6 and 7 will return part-way toward their normal position as shown in Figure 3.

A die 9 is then applied to the obliquely disposed portions 6 and 7, pressing them into the plane of the slide and completing the latter. If it is desired to enclose and conceal the joint 5 with in a ferrule, the ferrule blank 4 having its sides preferably slightly convergent, is placed upon the web in position to receive the free ends of the portions 6 and 7 as the latter are flattened by the die, the sides of the ferrule blank being bent over the free ends of the portions 6 and 7 and crimped thereupon by the same act of pressure by which said portions are brought into the plane of the frame 2.

The assemblage of the web and slide by the method above described will be found more efficient inloperation than an assemblage made by threading the Web through the slide in the .usual manner, since by the novel method it is possible to narrow the spaces between the frame side members and the middlebar, thus producing a superior degree of friction between the web and the slide.

A variant of the method is illustrated inTFigures 7 and 8 in which the frame-z comes to the assembling operation with the-portions 6 and 7 already set at right angles tothe planeof the frame. The spreader may be thus dispensed with. The folded web is laid down upon the frame and. suitable dies ll and l2 press1 the portions (Sand "'7' into an oblique position as shown L igure fi whereupon the die 9 presses vertically upon theportions B and 7 flattening :them lintothe plane of the frame ,2, the dies 11 and 12 fi ieanwlfl feqe'dine- In thecarrying out of the novel method of this invention the 1 nature of the slide ,is immaterial, providing that the middle bar is capable of opening at some point so as to admit the ,folddfleb to "a position beneath said middle bargand above theframe.

What I claim is: 1. Methodof assembling a suspender web and a suspender slide in operative relation compris- .ing, folding thelweb so as to provide at least two layers at the point which is to be engaged by saidslide, providing a slide having a frame for engaging one side of the folded Web and a middle bar for engaging the other side, said middle bar bfiingiopen at an intermediate point to permit entrance of the folded web into said slide; bending the portions of said middle bar away from one another toprovide a-space substantially as wide as the Width of said slide, introducing said folded Web through said opening into a position between said frame and said middle bar, arranging ferrule blank on said web at the point to be overlain bythe-free'ends of the portions of said rniddlebar, and closing said opening bybending said middle bar into substantially thesaine plane as saidframe and closing said ferrulelipon the adjacent ends of theportions of saidmiddlabar.

2.,Methodof forminga draw loop of ,suspender webbing and as l bling it inoperative relation to a s uspender slide without threading it-between the middle andendbars. of said slide, comprising foldinggthc .web so as to provide a loop, providing a slide having a substantially rectangular frame fromtne lateralpertions of whichthe component partor parts of a dividediniddle bar rise at a substantial angle to the plane of'said frame, introducing the two layers of folded webbing through thegap afforded by said divided middle bar, to

a position against :said frame, and closing said gap by bending the part or parts of saidmiddle ;bar into substantially the plane of :said frame.
